NOTE: VNX should work with libvirt versions from 0.7.5 to 0.8.5 (it has been mainly tested with 0.7.5 and 0.8.5). Note that, although libvirt 0.7.5 is available as a package in Ubuntu 10.04, it has some problems related with the Apparmor profiles configured for libvirt. If you disable Apparmor (with "/etc/init.d/apparmor stop"), VNX will work with libvirt 0.7.5 installed as package, however we recommend to download and compile version 0.8.5 as described above, in order to maintain Apparmor in your system.

Install Sys::Virt perl module:

For Ubuntu 10.04, just install the libsys-virt-perl package

apt-get install libsys-virt-perl

For Ubuntu 9.10, as Sys::Virt library is not available as a package, install it manually:

Check that the hostname is correctly configured (in /etc/hosts it has to appear in the 127.0.0.1 and ::1 lines). If not configured you could get the following error when accesing virtual machine consoles:

virsh console ubuntu
error:Falló al obtener nombre del host local

Disable host firewall or, alternatively, allow the services you want to use among virtual machines.
